r This invention relates toattachmentsfor internal combustion engines,the object. of

the invention beingto provide novel means is to provide means forheating the air after it has been treated, and prior to its passage tothe carburetor to increase the efficiency of the engine. V

A still further object of the invention is ,toprovide a device of thischaracter which may be readily and easily applied to motor vehicleconstruction, eliminating the-necessity of making alterations in theconstruction to install the device. v With'the foregoing and otherobjects in view which will 'appear as the' description proceeds, theinvention resides in the combination and arrangement of parts and inthe 1. details of constructionhereinafter described and claimed, itbeing understood that changes in the precise embodiment of'the inventionherein disclosed, may-be made within the scope ofwhat is claimed,without departing I 80 from the spirit .of the invention. 1 9

' Referringto the drawings in detail, the:ref-.

erencecharacter 5 indicates an internal combustion enginewhich issupplied with a shaft 6 on which the pulleys 7 and 8 are mounted,

the] pulley 8 transmitting;movement to the pulley 9, 1gou nted on theshaft'7, through the belt 1 .1

. Pulley *6 transmits movement ,to the pulley 7Y through the medium of abelt that operates thereover. The pulley 16 ismounted on the fanshaft'fi and receives motion there- Mounted on theshaft-7 "is a blower 8operating in the housing '9. which is formed withselongated openingslOfor theirecep' .The blower8 operateson the ball bearings- 11 thatsurround the bearingmember 12 that in turn isformed on the shaft 7 asclearly shown by Figure ,2 ofthe drawings so that the fan will; operatefreely;

' Openings 13are formed in one wall-'ofthe blower housing so thatastheblower 8 is rotated' within the housing, air will be drawnthrough-the'opening; where'it is passed through the outlet opening 14 ofthe housing,

pipe'15' formed which communicates with the integral .withthehousing. A

Th device also includes awater tank that communicates with the pipe 15through.

the-pipe 17' in such a way that air. will be blown througlrthe pipes 15and 17 i and -.di-

rected to=the interior of the tank "161' l Pivotally' 'mounted. adjacentto the lower end of the pipe l8 which is in communication with th Pipe17 is a pipe 19-.whichhas a dowrn wardly extended end portion adapted tolie under the level of the water in the tank- 16 so that in order forair to pass from the employed for securing thetank 16 to the'en gineconstruction. V v

The reference character 23 indicates the outlet pipe for the tank 16,which pipe communicates with the valve casing 24 to supply filtered airthereto. The valve operating within the casing24, compriseslateral disksthe pipe 27.

25 and 26 respectively, the disk 25 being provided with circularopenings 27 that establish communication between the interior of thevalve casing and pipes 39 and 44 respectively, which pipes extendthrough openings in the rear side of the valve casing. A'pipe 47 alsoextends into the valve casingat'the-front side thereof and providesdirect communication between the casing and carburetor of the enginewith which the device is used."

The disk 26 is'supplied with a single opening which-may be brought intoregistry with These disks 25 and 26 are I iounted on the shaft 30 tomove therewith, and are held in spaced relation witheach other by meansof the coiled spring 31 which also acts to hold thedisks intocloseengagementwith the inner surfaces of the walls of the casing. Thepipe 39' connects with the heating chamber '40 that. surrounds V theexhaust pipe 41 of the engine in spaced relation therewith so that airpassing through i the pipe 39 will be heated as it passes into theheating chamber 40. V A pipe 42 connects with the heating chamberadjacent to the upper end thereof, and connects with the union 46 thatinturn is supported on the heating chamber 45 mounted on the exhaustmanifold 45 oftheengine to the end that air which has been heated,'andwhich passes through the pipe '42 may be further heated by its passagethrough'the heating chamber 45., Pipe 44 establishes communicationbetween the valve casing 24 and union '46. The referencecharacter 46,designa'tesa pipe thatleads-from the heating chamber 45 to thecarburetornot shown, so that the air passing through the heating jchamber45 maybedirected tothe carburetor. 1 y I p p The controllinglrod isindicated-by the reference character 34 and connects with-the shaft30'at one end of the rod, the opposite 1 end of-"the rod extending to aposition in proximity to the operators seat where itis provided with ahandle 35 carrying a lockin pin 36 adapted to move into the openings 3formed in the disk 38 that constitutes a part of, the support for theoperating rod 34.

l/Vater is supplied to the tank 16 through the filling pipe 50 which issupplied with a cap 51 to close the outer end thereof. At the bottom ofthe tank is a discharge pipe 52 which is normally closed by the. cap 53so that should it be desired to drain. the tank and remove the sedimenttherein,.this may be-accomplished byremoving the cap 53.

The operation-lofthe devices is as follows:

During summer running the valves are moved so that the opening in disk26 will register with pipe 47 it being understood that the disk 25 is soarranged with respect to the disk 26, that when, the disk 26 is; ina'posiing to-the carburetor, the rod 34 may be op-.

erated to cause'one of the openingsof the disk 25 to register with thepipe 44, the pipe 47 being closed by the disk 26; Thus it will be seenthat air may now pass through the pipe 34 in the direction of the arrowA,

' through the heating chamber 45 and through pipe 46 wherethe heated airis delivered to the carburetor which is connected with. the pipe 46.- Fg Inmoderately cold weathenthe rod'34 may be operated to causethe'ropenings 27 of the disk 25 to register with the pipes 39 and 44whereupon the air passing throughthe valve casing, will passthroughpipes 39 and 44tsimultaneou'sly, a portion of the air pass; ingthroughthe heating chamber 40, through pipe 42from where it passesthrough the union'46 and into the heating'chamber 45'.

K In extremely cold weather therod 34n1ay be operated to cause theopenings ofthe disks 25 and 26-that register with the pipes 44and 47respectively,to be closed,- one of the open ings to the disk, 25 beingin registry with the pipe 39;to theend that the air will .take'thedirection of travel as shown by arrows B in Figure 1 of the drawings,whereupon the air will be heated by its passage through theheatingchamber-40, pipe 42, union 46aTnd heating chamber-4 5;

2. In combination with the carburetor and exhaust manifold of aninternal combustion engine, an air mixing and filtering devicecomprising a water tank, 'means for forcing air through the water in thetank, a drumlike valve casing, a pipe establishing communication betweenthe tank and valve casing, heating chambers, pipes for establishingcommunication between one side of the valve casing and heating chambers,a pipe establishing communication between the valve casing andcarburetor, disks having openings, positioned within the valve casing,and means for operating the disks to bring the openings of one:
